SPECIFICATION forming part of Letters Patent No. 657,317, dated September 4, 1900.

Application filed December 26, 1899. Serial No. 741,498. No model.)

State of Massachusetts, have invented an 1111-,

provement in Files for Proofs, Copy, &c., of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts. I

This invention has for its object the production of a strong, cheap, and efficient filing device for papers, particularlyadapted for use in filing proof-sheets orcopyin printingoifices and the like.

ln accordance with my invention thefiling device comprises an extended resilient ho1d-' ing-prong, a guard for the pointed end thereof, a brace, and an attaching portion, all formed of a single piece of stout Wire bent into proper shape, one of its ends being screwthreaded to form a means of attachment for the device and the other end pointed and forming the prong.

Figure 1 is a perspective view of a filing device or copy-holder embodying one form of my invention, a piece of paper being shown on the prong. Fig. 2 is a side elevation thereof, showing the preferred mode of attachment, the support beingshown in section; and Fig. 3 is a vertical transverse section of the device on the line 00 as, Fig. 2, looking toward the left.

In carrying out 'my invention in the embodiment thereof herein shown I take, a piece of stout strong wire a of proper length and brace and arch A being at the same side of the straight branch at. The lower end of the brace is then bent to form a closedloop a the free end of the loop being turned around the brace at a and extended substantially parallel to sustain the weight placed on the prong.

I then bend the branch ato form a resilient holding-prong a the pointed extremity a thereof being extended adjacent the bend a of the arch A, the bend forming a guard to protect the point of the prong.

The device is secured in place by screwing the threaded attaching portion a into the supporting object B, Fig. 2, until the loops a airest against its face, and as the device is intended to be used with the prong a in substantially-horizon tal position belo \v the guard the brace a with the loop a, will operate X0 t the same time the weight is resisted by the stiffness of the branch at and the divergent branch a the looped inner end (1? thereof bearing against the. vertical face of the supporting object B. Thus one portion of the device serves to support and strengthen another, and as the weight applied to the prong is below the attaching portion a there is no tendency of the device to turn about said portion a When a sheet is to be filed, it is bent and pushed onto the pointed end of the prong, as at M, Fig. 2, and passed along the prong until the head M of the sheet is inside of the guard a, (see Fig. 'l,) the main body of the sheet depending from the prong, so that it cannot be accidentally removed therefrom. When any particular sheet of a number on the prong is to be removed, a smart downward pull serves to tear it off without disturbing any of the other sheets, while access is readily had at any time to any sheet to examine its contents.

The device is particularly adapted for use in printing-oflices where large quantities of proof-sheets and copy are in constant use and which must be convenient of access for examination or removal, for the sheets can be quickly filed until needed.

The guard a'in connecting with the projectin g arch A protects the fingers and hands .of the user from the sharp point of the pron Strength, durability, simplicity, and cheapness, combined with ease of manipulation, constitute the salient and important features of my herein-described invention.

Having fully described my invention, what I claim, and desire to secure by Letters Patent, is-- outer end pointed and adjacent and protected by theguard, a supporting-brace connecting the inner end of theprongwith the branch" 1.
